The turning point came when the community realized the BG2-U01 was virtually identical to the international Ascend G525. The Chinese and European markets had different bootloaders and radio firmware, but the kernel source was similar.
The scene shifted to XDA Developers and Chinese forums (like Baidu Tieba and the now-defunct Vmall forum). The "Holy Grail" for this device was the TWRP (Team Win Recovery Project) port.
Once a working custom recovery was ported from the G525 to the BG2-U01, the floodgates opened. The most popular ROMs weren't built from source (because Huawei was stingy with kernel sources) but were ports from similar Qualcomm devices like the HTC Desire or the Galaxy S3 Mini.
The Big Three ROMs of this era:
Updating the Huawei MediaPad T3 7 3G (BG2-U01) with a custom ROM is a challenging process due to the device's age and Huawei's restrictive policies regarding bootloader unlocking. The Critical Hurdle: Bootloader Unlocking

Official Status: Huawei officially stopped providing bootloader unlock codes in 2018.
Current Methods: There is no free, official way to unlock it anymore. Some third-party services claim to provide codes for a fee, but these are often unreliable or considered "shady" by the community.
Hardware Dependency: The BG2-U01 uses a Spreadtrum/Unisoc SC7731G chipset. Some advanced tools like Pandora Box support Unisoc CPUs for flashing, but these usually require professional-grade hardware licenses. Available Software Options
Because this tablet is relatively under-supported by the major custom ROM communities (like LineageOS), your options are limited:
Stock Firmware Reflashing: If you are trying to fix a "bricked" or slow device, you can re-install the official Android 7.0 stock firmware using the SD Card Update method. The turning point came when the community realized
GSI (Generic System Images): Since the device launched with Android 7.0 (EMUI 5.1), it likely does not support Project Treble, which is required for modern GSI ROMs.
Community Forums: The most active discussions for this specific model, including experimental builds or specialized debloated stock ROMs, are found on forums like 4PDA. Summary of Specifications (BG2-U01)

In 2024, installing a Custom ROM on the Huawei BG2-U01 is purely an experimental or nostalgia-driven project. The phone cannot run modern apps like banking apps, Uber, or complex games due to API level restrictions and hardware limitations. However, if you have this phone lying around, flashing CyanogenMod 11 (KitKat) is the best way to turn it into a functional MP3 player, WiFi device, or "dumb phone" for calls and texts.
In the early 2010s, MIUI was a massive competitor to CyanogenMod. There are MIUI v5 and v6 ports for the BG2-U01. Updating the Huawei MediaPad T3 7 3G (BG2-U01)
